Watermarks can include customer-specific data like names, emails, and date, and are customizable with font face, font color, font size, vertical placement, and text.</p>

<li>Add a password to your PDF, and/or anti-copy, anti-print protections</li>

<li>Watermark is applied to <strong>all</strong> pages of the PDF (<a href="https://pdfink.com/" title="Upgrade to the full version" rel="nofollow ugc">upgrade to choose pages</a>)</li>
<li>Accommodates different page/paper sizes, and PDFs with various page sizes (letter, A4, legal, etc)</li>
<li>Secure & encapsulated: PDF Ink hooks into e-commerce download link clicks and checks for PDFs and maybe marks them – that’s it!</li>
